WP-0001: feedback channels, CI, pre-commit, telemetry docs

Add kaizen-agentic feedback CLI, Gitea issue templates, CI workflow,
pre-commit hooks, FEEDBACK/TELEMETRY docs, and cross-platform path tests.
Improve CLI registry error messages; remove agents_backup scaffolding.
Apply black formatting across src/tests for CI consistency.

+# Telemetry and Agent Effectiveness Tracking
+
+WP-0001 T04 design — aligned with ADR-004 and WP-0004 ecosystem integration.
+
+## Two layers (do not merge)
+
+| Layer | Question | Mechanism |
+|-------|----------|-----------|
+| **Project** | How is agent *X* performing in *this repo*? | `kaizen-agentic metrics record` → `.kaizen/metrics/` |
+| **Fleet** | How are coding sessions performing *across repos*? | agentic-resources Helix Forge |
+
+kaizen-agentic **does not** ship a parallel session transcript ingestion pipeline.
+
+## Project telemetry (implemented)
+
+Memory-enabled agents record per-session outcomes at close:
+
+```bash
+kaizen-agentic metrics record <agent> --success --time <s> --quality <0-1>
+kaizen-agentic metrics optimize [agent]
+kaizen-agentic memory brief <agent>    # includes Performance Summary
+```
+
+Optional fleet correlation via `HELIX_SESSION_UID` (see
+[integrations/helix-forge-correlation.md](integrations/helix-forge-correlation.md)).
+
+## Fleet telemetry (agentic-resources)
+
+Helix Forge owns session capture, digest storage, baselines, and weekly retro.
+kaizen-agentic consumes correlation fields only.
+
+## CLI install / usage analytics (future)
+
+Potential v1.1 additions (not yet implemented):
+
+- Opt-in anonymous counters on `install` / `memory init` (no PII, no project paths)
+- Aggregate effectiveness reports via `metrics list` across a monorepo checkout
+
+## tele-mcp evaluation (deferred)
+
+[tele-mcp](https://gitea.coulomb.social/coulomb/tele-mcp) is a candidate MCP adapter
+for IDE-level telemetry (WP-0001 note). Assess before depending on it. Project and
+fleet layers above satisfy INTENT's "measurable agents" requirement without tele-mcp.
+
+## Feedback loop
+
+User experience feedback uses [FEEDBACK.md](FEEDBACK.md) and Gitea issue templates —
+separate from execution metrics.
